srEoI roA'rroN man -ta Letters Patent No. e9s,o57, dated April 22, 19o'2. Application filed August 28,1901. Serial no. 73,620. (No model.)

To all whom; it may concern: I

Be it known that we, GEORGE HENRY Ronn- MAN and GEORGE OU TIs MILLER, citizens of the United States, residing at Oardingtomin the county of Morrow and State of Ohio; have invented a newand useful Can Holder or Jacket for Can-Capping Machines, of which the following is aspecification.

This invention relates to the art of capping tin cans after they have been filled,'and has for its object to provide means whereby any Ordinary capping-machine may be adapted for capping cans of different sizes without requiring that the machine be adjusted'for each sizeofcan. F

Heretofore can 7 capping machines have been capable of capping but one size of can at a time and also require to be adjusted throughout when changing from one size of can to another, whereby it is necessary to ac cumulate cans of corresponding sizes, so that each size may be independently run through themachine, the latter being adjusted when changing from one size of can to another. It is furthermore apparent that considerable de lay is occasioned byathe repeated adjustments of the machine, and also, in arranging the "output of a factory to accumulate large quantities of filled cans of corresponding size, so as to keep the capping-machine busy.

In view of the disadvantage now presented in ordinary can-capping machines, as above pointed out, it is the essentialobjeotof our invention to arrange for runningrcans of different sizes through the same machine, so

that they may be capped regardless of the size thereof, and. thereby to "obviate the necessity for stopping the machine to adjust the same for each size of can.

The inventionconsists, essentially, in pro viding a jacket or holder corresponding in size to the largest standard size of can and adapted to contain a smaller size of can, wherebya plurality of cans of different diama eters may be adjusted to correspond to the largest size of can, and all of the cans may properly cooperate with the conveyor mechanism of the machine, so as to be fed to the capping apparatus thereof.

In the drawings, Figure 1 is a perspective view of a can holder or jacket embodying the present invention,a can being contained within the holder or jacket. Fig. 2 is a longitudinal sectional View thereof. Fig. 3 is atop plan view of the jacket or holder, the can being omitted.

' Like. characters of reference designate cor responding parts in all the figures of the drawings.

In carrying outthe present invention it'is designed to provide a jacket or carrier,which is preferably made of tin or other sheet metal, and embodies an outer shell 1 and an inner shell 2, which are connected by the top and bottom bands or rims 3 and 4, respectively,

thereby forming a hollow open-ended jacket which is ordinarily cylindrical in shape for the accommodation of the common cylindrical tin cans, although it is contemplated to employ other shapes'in connection with polygonal cans.

- One end of the holder or jacket, preferably the upper end thereof, is free from interior projections or obstructions, so as to facilitate 1 the introduction of a can into the jacket, and the lower portion of the jacket is provided with a support for the can, preferably'in the form of a plurality of projections 5, extendingradially inward from the inner shell of the device and adjacent to the bottom edge thereof. It is preferable to have a skeleton or spider-like can-support rather thanto provide a solid bottom, as the former construction is'more sanitary and permits of a ready cleansing of the device. 1 1

' It will be understood that it is designed to V have the holder or jacket of a diameter equal to the largest standard size of can and slightly longer thansuch size of can, so that the distance between the top of the jacket and the can-support formed by the projections 5 may be equal to the smaller size of can which is designed to be received within V the jacket, so that .the top of the can may be flush with the top of thejacket, andthereby exposed to the action of the capping apparatus when the can and'holderhavebeen fed thereto.

In employing the present device a filledcan 6 which has not yet been capped is inserted through the open top of the jacket and supported therein upon'the can-support 5, and

too

this combined can and jacket is applied to the conveyor of the capping-machine in the manner of an ordinary can which is not provided with a jacket.

It will now be understood that in applying the jacket to smaller cans the latter and the jacket have a combined diameter equal to a larger size of can to which the capping-machine has been adjusted, so that the jacketed and unjacketed cans will be fed alike through the machine, and therefore it is not necessary to first run a plurality of cans of one size through the machine and then stop and adjust the machine for the other size of cans.

Of course the filling-openingsand caps of cans of different sizes are correspondingly different in size, and therefore it is necessary to adjust the acid-applying brushes and the soldering-irons of the machine to alternately correspond with the different sizes of capsthat is to say, they should be arranged for alternately capping first one size and then the other size or to cap two cans of one size and then one can of another size or any other preferred arrangement of cans.

From the foregoing description it is apparent that the essential object of the present invention is to provide means whereby cans of different diameters may be rendered capable of being eifectually taken up by the feed mechanism of a can-capping machine, where by it will be understood that each jacket or holder has the same external diameter, but varies in internal diameter according to the difference in size of the smaller cans. In other words, each jacket or holder will fit but one size of can, as the latter must snugly fit the holder.

What we claim is 1. An attachment for can-capping machines consisting of a can holder or jacket in the form of a hollow body having an external shape and size corresponding to that of the largest can of a type to be fed to the machine and capable of snugly receivinga smaller can, the interior of the body corresponding in shape thereto, and the'top of the body having an opening to expose the top of a can contained therein to the capping apparatus of the machine.

2. A can jacket or holder for can-capping machines, embodying a hollow body having an open end for the reception of a can, and to expose the cap end thereof, the external diameter of the holder or jacket being equal to the largest standard size of can, and its inner diameter corresponding to that of a smaller size of can.

8. A can jacket or holder for can-capping machines, embodying a hollow body having an open end for the reception of a can, and to expose the cap end thereof, the external diameter of the holder or jacket being equal to the largest standard size of can, and its inner diameter corresponding to that of a smaller size of can,and a can-support within the jacket and located above the bottom thereof.

4:. A can jacket or holder for can-capping machines, comprising a hollow open-ended body having an external diameter equal to that of the largest standard size of can, and its internal diameter being equal to a smaller size of can, and a plurality of lateral inwardlydirected projections carried by the inner side of the holder and slightly above the lower open end thereof to provide means for supporting a can within the jacket or holder.

5. A can jacket or holder for can-capping machines, comprising an outer shell, an inner shell, opposite rims or hands connecting corresponding end edges of ihe shells, and an inner can-support adjacent to the lower end of the body.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
